For selectivity test, a series of mixed solutions of sensor 1
and different metal ions were prepared. The each test
solution was prepared by placing 0.05 ml of the metal ion

Job's plot measurements. The stoichiometry of
complex can be estimated by Job's plot via the measure-
ment of absorbance and fluorescence spectra. Job's plot
was drawn based on the measurement of a series of
solutions in which the molar concentrations of metal ion
and ligand vary, but their sum remains constant. The
absorbance or fluorescence of each solution was measured
and the Job's plot was obtained by plotting the maximum
value of absorbance or fluorescence against the mole
fraction of metal ion or ligand. The maximum or the
inflection point on the Job's plot appear at the mole ratio
corresponding to the combining ratio of the complex.
